If you are a homeowner or business owner in Pomona, we would be glad to help and to treat your home or business like our own. We answer the phone 24/7 at (909) 312-4516. Pomona is one of the oldest cities we serve, incorporated in 1888, with Victorian and Craftsman homes downtown from the 1880s-1910s. Plumbing here often means working with original cast iron, galvanized, and older lead-soldered copper. Downtown (91766) and the Cal Poly area (91768) have heavy student-rental concentrations, so multi-unit and apartment work is common. Phillips Ranch (91766 south) is a master-planned hillside community built from 1965 through the 1990s, with standard tract-home issues.
Sweetwater Plumbing is a licensed, family-owned plumber (CSLB #889182) serving Pomona and the Inland Empire, rated 4.8 stars across 588+ reviews.

What we see in each part of Pomona:
Victorian and Craftsman homes from the 1880s-1910s. Old plumbing, often original cast iron and galvanized, plus older lead-soldered copper.
Master-planned hillside tract built from 1965 through the 1990s. Standard tract-home work.
Mid-century neighborhoods. Aging galvanized pipe and water heaters at the end of their life.
Mix of older homes near Fairplex and newer infill construction.
Historic homes throughout. We repipe carefully to preserve original wall finishes and plaster.
Pomona was the "Queen of the Citrus Belt" by the 1920s, and its housing shows it. The Lincoln Park Historic District alone has about 820 homes on 230 acres built from the 1890s to the 1940s in Victorian, Craftsman, Spanish, and Tudor styles. That means genuinely old plumbing. From there the eras step forward: mid-century tracts in areas like Westmont, and the master-planned Phillips Ranch, built from 1965 through the 1990s. Few cities we serve have this range of housing ages.
The City of Pomona runs its own water and sewer system, with Golden State Water serving some bordering areas. It's hard groundwater, so expect mineral buildup in heaters and on faucets. In the historic districts the bigger story is the age of the service lines themselves, original materials that often predate modern code. Knowing your provider matters for hardness and backflow.

Our techs know Pomona well: the neighborhoods, the lot layouts and the access routes.
Pomona's housing runs from 1880s Victorians downtown to Phillips Ranch tracts built through the 1990s. Each era comes with plumbing patterns we've seen for years. We arrive expecting what's typical for Pomona and ready to diagnose what isn't.
Most of Pomona is served by the City of Pomona, with Golden State Water in some areas. We test backflow devices on your provider's schedule, handle the paperwork it requires and file the results for you.
In Pomona specifically, the most common calls we get are for old galvanized plumbing in the pre-1940 downtown homes, and for cast-iron drain failures and tree-root intrusion under Pomona's mature street trees. But the full range of work we do in Pomona includes:
Active leaks, no water, and sewer backups. Dispatched to Pomona 24/7.
Tank, tankless, gas, electric, hybrid. Pomona's older homes often need code-update work around the unit during replacement.
Pomona's postwar homes built on slab foundations can develop slab leaks where copper lines pass under the slab. We use electronic and acoustic detection and repair without tearing up floors when possible.
We handle natural gas lines for Pomona properties of all kinds. We pressure-test and leak-check every job.
In Pomona's older homes, the sewer laterals are often cast iron or clay, with root intrusion. Cable for blockages, hydrojet to clear roots and grease. Camera inspection on every main line.
In Pomona's older housing stock, failing galvanized supply lines are a regular issue. We repipe with PEX or copper, work in stages, and patch any drywall we open.
Original clay laterals are common in older Pomona neighborhoods. When they crack or roots get in, we line them in place or replace them. We work on cast-iron, clay, ABS and PVC lines, trenchless when possible.
Annual testing & certification for City of Pomona and Golden State Water requirements. We file the paperwork directly with your water provider on your behalf. We also install and repair backflow preventers.
Restaurants, retail, multi-unit and office properties in Pomona. Flexible, after-hours scheduling around your operating hours.
Sweetwater Plumbing's service area extends across San Bernardino, Riverside and eastern Los Angeles counties.
